Abstract

Procédé d’obtention et de traitement d’une image acquise par une gamma caméra, la gamma caméra comportant un détecteur configuré pour détecter des photons X ou gamma émis dans un champ d’observation (Ω) de la gamma caméra, pour obtenir une image reconstruite. L’image reconstruire correspond à une position de sources d’irradiation dans le champ d’observation, l’image reconstruite étant susceptible de comporter plusieurs régions d’intérêt correspondant à des points chauds. Le procédé comporte une sélection d’une région d’intérêt, de façon à déterminer une probabilité de présence du point chaud dans la région d’intérêt sélectionnée.
